您好,我正在尝试使用 Selenium 和 Python 为网站
我的代码如下:
BASE_URL = 'https://mail.protonmail.com/create/new?language=en'driver = webdriver.Chrome(executable_path='./drivers/chromedriver')driver.get(BASE_URL)river.find_element_by_xpath('//*[@id="username"]').send_keys('someStringValue')
执行以下代码后,出现错误:
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="username"]"}(会话信息:chrome=83.0.4103.97)
有什么建议吗?
Email Address 字段位于 中,因此您必须:
诱导 WebDriverWait 使所需的框架可用并切换到它.
诱导 WebDriverWait 使所需的元素可点击.
您可以使用以下任一

Hi I was trying to type the username field using Selenium and Python for the website https://mail.protonmail.com/create/new?language=en.
From the developer tool, I am able to inspect the item using CSSSelector/Xpath or other way. But when I am running the pthon script its not working. Screenshot attached:
My code is like the following:
BASE_URL = 'https://mail.protonmail.com/create/new?language=en'
driver = webdriver.Chrome(executable_path='./drivers/chromedriver')
driver.get(BASE_URL)
river.find_element_by_xpath('//*[@id="username"]').send_keys('someStringValue')
And after executing the following code, geetting the error:
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="username"]"}
(Session info: chrome=83.0.4103.97)
Any suggestion?
The Email Address field is within an <iframe>
so you have to:
Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use either of the following Locator Strategies:
Using CSS_SELECTOR
:
driver.get('https://mail.protonmail.com/create/new?language=en')
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"div.usernameWrap iframe[title='Registration form']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.input#username"))).send_keys("FunnyBoss")
Using XPATH
:
driver.get("https://mail.protonmail.com/create/new?language=en")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//div[@class='usernameWrap']//iframe[@title='Registration form']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='input' and @id='username']"))).send_keys("FunnyBoss")
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
